• skills/shared/references/explain-pattern.md — shared answer format and behavior
• skills/shared/references/methodology-framework.md — shared principles, hook architecture

• skills/rust-setup/references/analysis-checklist.md — how projects are analyzed

Example Questions

"Why clippy instead of an external linter?" → Dimension 2. Clippy is deeply integrated with the compiler, covering style, correctness, performance, complexity. No external tool matches its coverage.

"What's the coverage threshold?" → Dimension 1. 75% default; 60% new; 85% library.

"Why cargo-deny over cargo-vet?" → Dimension 4. cargo-deny covers advisories + licenses + duplicates + bans in one config file.

"Why is unsafe_code forbidden by default?" → Dimension 3. Most crates don't need unsafe. FFI/interop crates relax this.

"How does WASM support work?" → WASM-Specific Considerations section. Detection, testing, CI, and quality gate adaptations.

"How do I disable a check?" → Each check has a [check:*] comment marker. Delete the run_check block.
